How's the culture? Are devs actually busy and productive or is the the typical never ending wait for requirements to materialize that's so common at moribund large enterprises?
I certainly cannot speak for all teams, but most teams are fairly autonomous as long as they deliver. Like any big company, there are lots of stakeholders so that means that final decisions, for example a feature being in or out of scope, can take an unnecessary long time, but it does not mean you are stuck waiting. There are always lots of things to implement, refactor or improve that do not require a seal of approval.
